It's that time of the week again. The PS store has received yet another update. Leading this week's agenda is The Walking Dead - Episode 3, Metal Gear Solid Peace Walker HD Edition, and Rock Band Blitz.

Harmonix has announced that the instrument-less version of their popular music game, Rock Band Blitz, will be hitting Xbox Live Arcade on the 29th August, and PlayStation Network on the 28th. The game will cost a mere 1200 Microsoft Points / $14.99 USD.

Rock Band Blitz is Harmonix's latest music game, which is basically the core Rock Band experience but ditches the plastic instruments. Part of the appeal of Blitz is that all of the downloadable content purchased for previous Rock Band titles can be played on the new game.

However, Harmonix plans to release 25 core songs that will come with the game, and 15 of them have been revealed.

It seems that Harmonix is working on yet another project, and this time it seems to be a new Kinect game. The developer has posted several job listings, and each one is looking for personnel to work on "a unique motion-gaming IP."
